REV.-B

NOTES 1. “Return” denotes a twisted pair return line connected to

signal

ground. When interfacing

the printer to the host, use twisted pairs for each signal.

Shield

the twisted pairs, and connect

the shield to GND in order to reduce interface.

2. All interface conditions are based on TTL levels. Both the rise and fall times of all signals

must be less than

0.2Ks.

3. Refer to the Parallel Interface Timing Chart for the timing of the signals.

4. Data transfer protocol must not ignore the

ACKNLG

or BUSY signal. (Data can be transferred

either after recognizing the

ACKNLG

signal or when the BUSY signal is LOW.)

5. The AUTO FEED XT and

SLCT

IN signals are valid when they are not fixed to LOW level by

the DIP switch or jumper.

6. Printing tests, including those of the interface circuits, can be performed without using

external equipment: set interface connector data lines 1-8 to the desired code (a floating

signal will be a logical 1, and a grounded signal will be a O) connect the

ACKNLG

signal

to the STROBE signal.

7. The PE signal is valid when the ERROR signal is LOW.
